Abstract

The present invention relates to a touch sensor integrated display and a driving method thereof. The touch sensor integrated display includes: a display panel including a touch screen with a touch sensor; a data driving circuit for driving data lines of the display panel; and a timing controller, the The timing controller is used to generate a control signal for controlling the potential of the output terminal of the data driving circuit in a vertical blank period between adjacent vertical periods. The control signal selectively floats the source output channel of the data driving circuit or selectively sets the potential of the source output channel to a predetermined voltage during the vertical blank period.

Description

technical field [0001] Embodiments of the present invention relate to a touch sensor integrated display and a driving method thereof. Background technique [0002] Touch screens have replaced push button switches as user input devices to provide slim and light home appliances and electronic equipment. A touch screen is a device configured such that a user directly touches the screen without using other input devices and inputting information. Currently, touch screens are being used in the mobile phone market and have been widely used in most IT products. [0003] A touch screen used in a display device includes a plurality of touch sensors and may be attached to a display panel of the display device. Based on their touch recognition methods, touch screens can be classified into resistive touch screens, capacitive touch screens, electromagnetic touch screens, and the like. A capacitive type touch screen that senses a position where capacitance changes and a touched portion...
